Sami Erol Gelenbe (brought into the world 22 August 1945) is a Turkish-French PC researcher, electronic architect and applied mathematician who is a Professor in the Institute of Theoretical and Applied Informatics of the Polish Academy of Sciences, and is additionally subsidiary with the I3S Laboratory of the University of Cote d’Azur (Nice). Beforehand he was a led teacher at University of Liege (1974-1979), University Paris-Sud (1979-1986), University Paris Descartes (1986-2005), Duke University (1993-1998), the University of Central Florida (1998-2003) and Imperial College (2003-2019). Known for spearheading the field of displaying and execution assessment of PC frameworks and organizations all through Europe, he imagined the arbitrary neural organization and the eponymous G-organizations. His honors incorporate the Grand Prix France Telecom (1996) of the French Aademy of Sciences, ACM SIGMETRICS Life-Time Achievement Award, the Oliver Lodge Medal of the UK’s Institution of Engineering and Technology (2010), and the “In Memoriam Dennis Gabor Award” (2013)  of the Hungarian Academy of Sciences.
Gelenbe was brought into the world in Istanbul in 1945, to Yusuf Ali Gelenbe, a relative of the eighteenth century Ottoman mathematician Gelenbevi Ismail Efendi, and Maria Sacchet Gelenbe from Cesiomaggiore, Belluno, Italy. After a youth spent in Istanbul and Alexandria (Egypt), he moved on from Ankara Koleji in 1962 and the Middle East Technical University, Ankara in 1966, where he won the K.K. Clarke Research Award for an undergrad theory on “fractional transition exchanging attractive memory systems”. Awarded a Fulbright Fellowship, he proceeded with his examinations at Polytechnic University, where he finished a graduate degree and a PhD postulation on “Stochastic automata with basic limitations”, under the oversight of Edward J. Smith.
After graduation he joined the University of Michigan as an associate teacher. In 1972, on leave from Michigan, he established the Modeling and Performance Evaluation of Computer Systems research bunch at INRIA (France), and was a meeting partner teacher at the University of Paris 13 University. In 1971 he was chosen for a Chair in Computer Science at the University of Liège in Belgium, where he joined Professor Danny Ribbens in 1973, while staying an exploration chief at INRIA. In 1973, he was granted a Doctorat d’état ès Sciences Mathématiques from the Paris VI University with a proposition on “Modèlisation des systèmes informatiques”, under Jacques-Louis Lions. He stayed a dear companion of Professor Ribbens and of the University of Liège, and in 1979, he moved to the Paris-Sud 11 University, where he helped to establish the Laboratoire de Recherche en Informatique and its PhD Program, prior to joining Paris Descartes University in 1986 to establish the Ecole des Hautes Etudes en Informatique.
Gelenbe was named New Jersey State Endowed Chair Professor at the New Jersey Institute of Technology from 1991 to 1993, and afterward in 1993 he was selected to Duke University where he was the Nello L. Teer Chair Professor and Head of the Electrical and Computer Engineering Department until 1998 when he moved to the University of Central Florida, and established the School of Electrical Engineering and Computer Science and made the Harris Corporation Engineering Center 
In 2003, Gelenbe was offered a Chair at Imperial College London as the Dennis Gabor Professor in Computer and Communication Networks  and Head of Intelligent Systems and Networks, from which he resigned in 2019. He is presently a Professor in the Institute of Theoretical and Applied Informatics (IITIS) of the Polish Academy of Sciences.
Gelenbe developed the Random neural organization model and its polynomial-time learning calculation. He created the eponymous G-organization, a numerical model of the presentation of circulated frameworks and organizations with complex hub to hub collaborations, used to dissect dynamic asset distribution in interconnected frameworks. He has spearheaded research concerning the exhibition of multiprogramming PC frameworks, virtual memory the executives, information base dependability improvement, circulated frameworks and organization conventions. He shaped, drove, and prepared the group that planned the business QNAP Computer and Network Performance Modeling Tool. He presented the Flexsim Object Oriented methodology for the reenactment in assembling frameworks prompting a broadly utilized business item. He distributed the principal deal with versatile control of PC frameworks to upgrade time-sharing frameworks, and distributed fundamental papers on the presentation enhancement of PC network conventions and on dispersion approximations for network execution. He imagined the item structure queueing networks with negative clients and triggers known as G-networks. He presented another spiked stochastic neural organization model known as the arbitrary neural organization, built up its numerical arrangement and learning calculations, and applied it to both designing and natural issues. His creations incorporate the primary Voice-Packet Switch SYCOMORE for Thales, the irregular access fiber-optics neighborhood XANTHOS, a licensed confirmation control method for ATM organizations, a neural organization based inconsistency identifier for mind attractive reverberation filters, and the Cognitive Packet Network directing convention to offer nature of administration to clients  .
From 1984 to 1986 he filled in as the Science and Technology Advisor to the French Secretary of State for Universities. He established the ISCIS (International Symposium on Computer and Information Sciences) arrangement of meetings that since 1986 are held every year in Turkey, the USA and Europe to unite Turkish PC researchers with their worldwide counterparts. According to the Mathematics Genealogy venture, Gelenbe is positioned ninth worldwide among PhD managers in the Mathematical Sciences, including Computer Science, having graduated exactly 90 PhD students. 24 of his previous PhD understudies are ladies, including a Fellow of the Royal Academy of Engineering of Canada, and the previous Director General of Higher Education in France.
